If it were yours would you do this, I have no shortage of bamboo around the 3/4" size and a little smaller.

It's a pain to do this but I hate the bright metal roof you see on the inside and this is free but a lot of labor by me. I will do something that metal has got to be covered. Each section will be filled in so you see no metal, it would take a while but would be finished eventually.

The other idea would cover all the wood, bamboo reed fencing stuff with larger bamboo covering the seams and wherever it's needed. I think this idea would last longer ?

Looks great! You're lucky to have free bamboo to work with! I'm sure some more crafty ideas will come along for its use as well. If it dries to brown relatively fast I'd be cutting a bunch for trim work, tiki lights, shelving, just about anything 3/4" would be good for. And that bar rocks!
